A new study has provided potentially groundbreaking evidence of a link between exposure to toxic debris at New York’s Ground Zero and the development of cancer. The medical journal, The Lancet, reports male firefighters exposed to dust and smoke at the site of the 9/11 attacks have a 19 higher percent risk of developing cancer than colleagues who were not exposed. The finding comes just one month after the National Institute for Occupational Safety and Health issued there is insufficient evidence to draw a link between the 9/11 site and cancer. Firefighters and rescue workers have been unable to receive payments for cancer treatments because cancer is not covered under legislation providing care for 9/11 responders.
